Q1: What is a gas detector?
A1: A gas detector is an instrument for gas leakage concentration detection, including a portable gas detector, handheld gas detector, fixed gas detector, online gas detector, etc.
Q2: What does a gas detector detect?
A2: Combustible gases: Natural gas (methane), liquefied gas, coal gas (hydrogen), acetylene, pentane, alkynes, acetone, toluene, alcohols, hydrocarbons, light oil, etc.
Toxic gases: Carbon monoxide, hydrogen sulfide, ammonia, chlorine, oxygen, phosphine, sulfur dioxide, hydrogen chloride, chlorine dioxide and other toxic and harmful gases.
Q3: What is ppm of gas detector?
A3: Parts per million or "ppm" is often used as a fractional measure of concentration. For example, a methane (molecular) concentration of 2% means that 2 out of every 100 air molecules are methane. Likewise, a methane concentration of 2 ppm means that 2 out of every 1 million air molecules are methane.
Tips: How to maintain a portable H2 detector?
- The gas calibration has been done before leaving the factory. After installation, please do not change the components at will. If you need to replace it, you must re-calibrate it.
- The normal service life of a portable H2 detector is 3 years. Due to the difference in the use environment, its service life may be reduced, and inspection and maintenance should be carried out regularly every year.
- High-concentration hydrogen shock is forbidden in the parts to avoid poisoning the gas sensor and damaging the detector.
- During the use process, check whether the hydrogen gas detector is working normally, and the check period should be kept at 3 months at least.
